I shouldn't. The oleout32.dll that is probably causing this is installed by the installation program. But, somehow that may be a different version than the rest of the ole files which could cause the error.
The only thing that should happen is all of the automation files will be the same version after you install it. Which should remove the error. If not, then you'll only have a few more .dll files on your system.
If you want to be extra cautious, if they are on your system..back up these files before installation...
Asycfilt.dll
Oleaut32.dll
Olepro32.dll
Stdole2.dll
If you're running windows 2000, don't bother installing it. Nothing can be done that I know of.
